whats the location of the pcv valve on on a 2001 bmw 740il (e38)
In front of the engine slightly to the left and lower area of the throttle valve. It is a round black plastic canister supported by a teardrop shaped rubber with a cable connector at the top and 2 hose connections at the opposite end of the cable connector which are perpendicular to each other. BMW calls it the tank vent valve.
